26 FebWiring Almost Finished

More progress made over the past few evenings. Car is now completely wired up, save for the idle valve (which I won’t need on first startup) and IAT sensor. I still don’t know what exactly I’m going to do for air filtration and ducting, I quite like the idea of the flexible alloy ducting you […]

23 FebThe EFI Fuel Pump High / Low Pressure System

There’s a low pressure pump attached to the inner wing panel, and a high pressure pump built into a swirl pot, bolted to the boot floor with some mini exhaust bobbins. The low pressure feed is plumbed in, the low pressure return is about to be done – I’m just waiting on some fuel hose […]

22 FebEFI Update

Haven’t posted this week as I’ve been exhausting myself working on the car. Lots to show though, even if the finishing line still seems distant. Spent an evening cutting all the Megajolt wires and splicing in the corresponding Megasquirt ones to test the ignition control. This was so easy, though the next day when starting […]

19 FebPolishing Takes Bloody Ages

polished triumph spitfire inlet manifold

I ended up splitting this up into several 3 hour sessions after work, eventually turning the inlet manifold into something blingy enough to earn me street cred. Starting with this: everything was gone over with a fine scotchbrite pad to give me an even surface prep and to see where the manifold needed a lot […]

29 JanThe Manifold Is Finished!

Went to see Tim again today, what an adventure! Think I must have driven for about 8 hours in total (got stuck in traffic both in Bradford in the morning rush hour and Kidderminster in the teatime one).¬†¬†Torrential rain, pitch black deristricted country roads, and extreme winds on Saddleworth moor. Engine stuttering on the way […]

17 Aug320 Miles of Driving and 1 Fuel Injection Manifold

Here’s a few photos of what I’ve been up to today in my Spitfire. Left the house about 8am to drive down to see Tim (bestquality03), finally got there at 11am with no trouble at all, save for the wipers packing up on the motorway in torrential rain at 80mph 70mph (fusebox contacts…grr..), the cigarette […]

25 JunFuel Tank and Wideband Progress

I might have my wideband installed by the end of this week, today I took the gearbox tunnel off to figure out where it was going and centre punched the location just after the collector. Tight fit isn’t it!? Also topped up the gearbox oil while I was there, bloody hell replacing a mssing 0.2l […]

Starting to pick up the pace a bit with getting everything together for converting my 1500 to EFI. Current progress includes: EDIS wasted spark ignition has been bedded in and running flawlessly for a few months and many hundreds of miles now. 5/8″ UNF temperature Rover temperature sensor neatly installed and will work great with […]

21 DecInjectors Acquired!

Managed to get my fuel injectors this week, Bosch 280150749. These came out of a Rover 216, and were attached to a fuel rail. Doubt I’ll have any use for the rail though. I’ll use the o-rings on them now for fitting/testing, then buy new ones when the system is finished.

02 SepFuel Injection Manifold

fuel injection idea

This article kicks off a series on how to go about fuel injecting a Triumph Spitfire 1500. The plan is to first install a trigger wheel and Megajolt, taking care of the spark side of the ECU by making the small jump to electronic ignition. Once the Megajolt has been fully configured and all it’s […]
